Thanks Steve,
That's great that you ran the numbers I gave and cross checked it to full-sized "real life" kayak prices. It makes perfect sense to me to use the length to some degree, to at least get a base price. From there, it could go up or down depending on the quality of the work and how many (noticable) flaws are on it. It still takes about 60 hours or so to build, so you have to enjoy making them, because you won't get paid squat for your labor. I've built 6 models that are actually worth a damn and have yet to make a dime. But I have gained valuable experience and had an absolute blast in the process.

If my goal was to just make a higher hourly wage at selling model kayaks, I would choose to carve them or build SOF models. Neither of these take much time at all to build and would look just as cool on the mantle. Of these two, I would have more fun carving, because of the sensation I get seeing how neat a laminated block of exotic hardwoods changes into a kayak shape with just the touch of an angle grinder. I have yet to try it at the 4 or 5 foot scale, but I'm sure it'd be fun. Sand and varnish and you're done. Probably carve two or even three in a day. Okay, I gotta go now....
Thanks

: I took your proposed prices and played a little - (I'm not sure why, other
: than I like playing with numbers)

: The numbers you supplied delivers a best-fit straight line of
: Price=77.143*length+76.667, where Price is in $ and Length is in feet.
: This gives the following list for Price vs length.

: 1 $153.81
: 2 $230.95
: 3 $308.10
: 4 $385.24
: 5 $462.38
: 6 $539.53
: 7 $616.67
: 8 $693.81
: 9 $770.95
: 10 $848.10
: 11 $925.24
: 12 $1,002.38
: 13 $1,079.53
: 14 $1,156.67
: 15 $1,233.81
: 16 $1,310.96
: 17 $1,388.10
: 18 $1,465.24
: 19 $1,542.38
: 20 $1,619.53

: Given that a 17ft kayak goes for $5000 or so, this is off a bit. You could
: factor in that a model does not have bulkheads, rigging, etc and maybe
: come up with a nicely finished full-size model should cost - oh, I don't
: know - how about $3500?

: If you add 17 ft and $3500 to the list of price vs length and fit an
: exponential function to that, you get Price=167.8*e^(0.182*Length) and the
: following table: 1 $201.30
: 2 $241.48
: 3 $289.68
: 4 $347.50
: 5 $416.87
: 6 $500.08
: 7 $599.91
: 8 $719.66
: 9 $863.31
: 10 $1,035.64
: 11 $1,242.37
: 12 $1,490.36
: 13 $1,787.86
: 14 $2,144.74
: 15 $2,572.86
: 16 $3,086.44
: 17 $3,702.53
: 18 $4,441.61
: 19 $5,328.22
: 20 $6,391.81

: I don't know if this is helpful, but it looks like your pricing is not all
: that high to me. Like I said, I just like to play with the numbers ...
